I switched over to red sea coral pro after the tropic Marin dust up and lack of supply. Over the last few months I’ve noticed some residue when mixing. However this past last batch was horrendous. It is brown, caked on residue in my buckets and clogging my power head for mixing. So my two questions are
1. what the heck is this stuff?
2. What if anything is it doing to my tank chemistry?
I just ordered some tropic and will switch back.
